Using advanced tracing and evaluation techniques

The process of building an LLM-based application using a tool such as LlamaIndex is very developer-friendly since the framework abstracts away a lot of technical stuff. But at the same time, this complicates things, for the very same reason. When things don’t work as planned, developers need to have effective ways of understanding why. They have to peel back all these layers of abstraction in order to pinpoint the root causes. In other words, we need to be able to see the inner mechanics of our code, understand how different components interact, and be able to identify underlying issues. That’s where tracing becomes a really important feature. On the other hand, because we have so many tools available and so many ways of building our solution, we need a way to benchmark different combinations and determine the best mix of tools and orchestrations. That’s where evaluation comes into play. Evaluation is essential for...
